CARLINE AND PROCESS OF MAKING IT.

Specification of Letters Patent.

Patented J-uly 1917.

Application filed October 14, 1916. Serial No. 125,7131

T0 all'whom it mag concern: 7

Be it known that I, FRED MATHEWS. a citizen of the United States, and aresident of the city of Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Carlines andProcesses of Making Them, of which the following is a specification.

This invention relates particularly to truss carlines such as are usedfor freight cars having pitch roofs; and the objectof the invention isto produce a light, strong carline from light commercial rolled shapes,such as I-beams and Z-bars.

The invention consists in a carline formed by splitting the web of arolled metal shape in from each end nearly to the middle, and bendingapart the split portions until the split portions at opposite ends ofthe original metal shape converge and meet at their extremities, wherethey are secured together, thereby forming a truss.

The invention further consists in the details of construction of thecarlines shown in the accompanying drawings.

Further objects and details of the inven tion appear in connection withthe following description of the two carlines shown in the drawings; andwhat the invention consists in is further defined in the appendedclaims.

In the drawings, wherein the same reference characters designate thesame parts in the several views,

Figure 1 is a top plan view of a carline embodying the invention,showing it secured to the side plates of a car;

Fig. 2 is a side View of the same, the side plates being shown incross-section;

Fig. 3 is a plan view similar to Fig. 1 showing another carlineembodying the invention; and

Fig. 4 is aside view of the carline shown in Fig. 3.

The carline shown in Figs. 1 and 2 consists of top and bottom anglebars, integrally connected at the middle by a strut 12, and rivetedtogether at their ends to form a truss. The bottom bars 13 arehorizontal, and the top bars 14 are inclined up to their junction at themiddle. The horizontal bars form the lower chord of the truss, and theinclined bars are arranged over the horizontal bars to form the ridgeand downwardly sloping ends of the top chord of the truss. The top andbottom bars are angle-shaped, and are arranged with their horizontalflanges in contact at the ends and their vertical flanges up on the topbars and down on the bottom bars, projecting away from each: other. Altthe'middle, short angle bars 15 are riveted to the vertical flanges, oneon the top and the'othcr on the bottom. The upper flange of the topangle bar formsa horizontal seat upon which the ridge pole of thecar maybe supported and held by avertical bolt. The ends 16 of the horizontalflanges of the bottom bars 13 are bent downinside of the side plates 17;and the ends 18 of the horizontal flanges of the top bars are' bent overthe side plates. The ends of the top bars rest on the side plates, andthe downwardly bent ends of the flanges are bolted together through theside plates and secure the carlines to the side plates.

The carline shown in Figs. 1 and 2 is formed from an I-beam by slittingboth of its ends along the mid-line of the web nearly to the middle ofthe member. The slit ends are bent apart until the two portions of eachend extend in opposite directions, and converge with the two portions ofthe opposite ends. The flanges of the converging portions are pressedinto contact at the ends, and are riveted together. The ends of the websare cut out, and the ends 16 of the bottom flanges are bent straight atright angles to the webs to form brackets, and the ends 18 of the bottomflanges are bent straight out and down parallel to the ends 16 to formpockets for embracing the side plates.

In the carline 19 shown in Figs. 3 and 4, the top and bottom bars areformed from a Z-bar which is slit and bent at the middle as in thecarline described above. The top and bottom flanges 20 of the Z-bar areon the upper and lower edges, and the vertical webs lap and are rivetedtogether at the ends, in the carline shown in Figs. 3 and 4; but theymay be so bent as to be next to each other, as in the carline shown inFigs. 1 and 2, and the flanges of the angle bars pressed in contact witheach other at the ends and riveted together. The ends 21 of the flanges20 are bent down to provide sockets for the side plates like those ofthe carline shown in Figs. 1 and 2.

The invention is not restricted to the shapes and forms of metal-barsshown in the drawings; nor to the precise manner of making the carlinesdescribed above.

I claim the following as my invention: 7

1. A carline formed by splitting the Web of a rolled metal member ateach end, the splitting extending nearly to the middle of the member,bending apart the split endsto extend in opposite directions, said splitends converging at opposite ends of the carline, and securing saidconverging ends together near their extremities. I

2. A carline formed by splitting the Web of :1 rolled metal member ateach end, the splitting extending nearly to the middle of the member,bending apart the split ends to extend in opposite directions, saidsplit ends convergin at opposite ends of the carline,

and securing said converging ends together near their extremities, theextremities of said split ends being bent transversely t0 the carlinefor securing it to the side plates. 3. A one-piece truss member for acarline having a middle strut portion the ends of which diverge and formconverging end chord members Whichare fastened together at their ends,the top and bottom chord members of said truss having horizontalflanges, the top flange being extended over the side plate and thebottom flange terminating at the inner face of the side plate.

4. A truss member for a carline having a middle strut portion andconverging end chord members formed from a single piece of metal bysplitting its ends, spreading them apart, and securing the extremitiesof one pair of spread ends to the other pair of spread ends.

5. A member for a carline having an upright middle strut portion andconverging top and bottom end chord members spaced apart at the middleof the carline, said end chord members being integral with said middlestrut and lapped and riveted together at their ends to form a truss.

Signed at Chicago, 111., this 10th day of October, 1916.
